Skip to content Elite Mold Tech integrates metal and plastic with precision insert molding—perfect for electrical connectors, threaded inserts, and embedded structures.
Elite Mold Tech specializes in insert molding, a process that allows you to integrate metal, plastic, or other materials directly into your molded parts. This technique is perfect for applications where additional strength, electrical conductivity, or precise threading is required.
By embedding inserts such as metal fasteners, wires, or bushings into plastic parts during the molding process, we achieve stronger, more reliable components without the need for post-production assembly. This service is ideal for automotive, medical, and industrial applications, offering enhanced durability and performance.

Insert molding involves placing metal inserts into a mold before injecting plastic around them, creating strong, integrated parts. This process is ideal for producing components that require embedded elements such as threaded inserts or electrical contacts, commonly used in automotive, aerospace, and electronics.
With Elite Mold Tech, you can now access precision molding services for plastic and metal parts integration. Our Insert Molding service improves the strength, durability and functionality of components across many industries.
| Description | General Tolerance or Standard |
|---|---|
| General Dimensional Tolerances | ±0.005” (±0.13 mm) for molded features; in line with ISO 20457 for plastic parts |
| Insert Placement Tolerance | ±0.002”–0.005” (±0.05–0.13 mm) for manual or automated insert positioning |
| Insert Fit Tolerance | Press-fit inserts: ±0.001”–0.003” (±0.025–0.076 mm) Looser fit may be used if thermal expansion/shrinkage is expected |
| Hole Diameter (Post-Mold) | ±0.003”–0.005” (±0.076–0.13 mm), varies with core pin accuracy and plastic shrink rate |
| Shrinkage Compensation | 0.4%–2% depending on plastic type (e.g., ABS, Nylon); insert molding accounts for differential shrinkage between metal and plastic |
| Flash Tolerance | ≤ 0.004” (≤ 0.10 mm) at parting lines; critical sealing areas may require tighter control |
| Surface Finish | Ra 1.6–3.2 μm (63–125 μin) typical; can be textured or polished depending on mold cavity finish |
| Insert Material Compatibility | Brass, stainless steel, aluminum, and threaded components; must withstand mold temps (typically 250°C–350°C) |
| Assembly Accuracy | ±0.005” (±0.13 mm) for final assembled insert-molded part, depending on number of inserts and complexity |
